Remove dirt and dust using a
vacuum cleaner.
 Wipe off any excess dirt and
dust with a soft cloth damp-
ened with diluted detergent.
Use a diluted water solution of
approximately 5% neutral wool
detergent.
Wring out any excess water
from the cloth and thoroughly
wipe off all remaining traces
of detergent.
 Wipe the surface with a dry,
soft cloth to remove any
remaining moisture. Allow the
leather to dry in a shaded and
ventilated area.
■Caring for leather areas
Toyota recommends cleaning the
interior of the vehicle at least twice a
year to maintain t he quality of the
vehicle’s interior.
NOTICE
• Seats: Alkaline or acidic solu- tions, such as thinner, benzene,
and alcohol
●Do not use polish wax or polish
cleaner. The instrument panel’s
or other interior part’s painted
surface may be damaged.
■Preventing damage to leather
surfaces
Observe the following precautions
to avoid damage to and deteriora-
tion of leather surfaces:
●Remove any dust or dirt from
leather surfaces immediately.
●Do not expose the vehicle to
direct sunlight for extended peri-
ods of time. Park the vehicle in
the shade, especially during
summer.
●Do not place items made of
vinyl, plastic, or containing wax
on the upholstery, as they may
stick to the leather surface if the
vehicle interior heats up signifi-
cantly.
■Water on the floor
Do not wash the vehicle floor with
water.
Vehicle systems such as the
audio system may be damaged if
water comes into contact with
electrical components such as the
audio system above or under the
floor of the vehicle. Water may
also cause the body to rust.
■When cleaning the inside of
the windshield
Do not allow glass cleaner to con-
tact the lens. Also, do not touch
the lens. (
P.237)

clean the rear window, as this
may cause damage to the rear
window defogger heater wires
or antenna. Use a cloth damp-
ened with lukewarm water to

When trouble arises
6Open and close any of the
doors of your vehicle with the
power switch OFF.
7 Maintain the engine speed of
the second vehicle and start
the hybrid system of your
vehicle by turning the power
switch to ON.
8 Make sure the “READY” indi-
cator comes on. If the indica-
tor light does not come on,
contact your Toyota dealer.
9 Once the hybrid system has
started, remove the jumper
cables in the exact reverse
order from which they were
connected.
10 Close the exclusive jump
starting terminal cover, and
reinstall the fuse box cover to
its original position.
Once the hybrid system starts,
have the vehicle inspected at
your Toyota dealer as soon as
possible.
■Starting the hybrid system
when the 12-volt battery is dis-
charged
The hybrid system cannot be started
by push-starting.
■To prevent 12-volt battery dis-
charge
●Turn off the headlights and the
audio system while the hybrid sys-
tem is off.
●Turn off any unnecessary electri-
cal components when the vehicle
is running at a low speed for an
extended period, such as in heavy
traffic.
■When the 12-volt battery is
removed or discharged
●Information stored in the ECU is
cleared. When the 12-volt battery
is depleted, have the vehicle
inspected at your Toyota dealer.
●Some systems may require initial-
ization. ( P.523)
■When removing the 12-volt bat-
tery terminals
When the 12-volt battery terminals
are removed, the information stored
in the ECU is cleared. Before
removing the 12-vo lt battery termi-
nals, contact you r Toyota dealer.
■Charging the 12-volt battery
The electricity stored in the 12-volt
battery will discha rge gradually even
when the vehicle i s not in use, due
to natural dischar ge and the drain-
ing effects of certain electrical appli-
ances. If the vehicle is left for a long
time, the 12-volt battery may dis-
charge, and the hybrid system may
be unable to start. (The 12-volt bat-
tery recharges automatically while
the hybrid system is operating.)
■When recharging or replacing
the 12-volt battery
●In some cases, it may not be pos-
sible to unlock the doors using the
smart key system when the
12-volt battery is discharged. Use
the wireless remote control or the
mechanical key to lock or unlock
the doors.
●The hybrid syste m may not start
on the first attempt after the
12-volt battery has recharged but
will start normally after the second
attempt. This is not a malfunction.
●The power switch mode is memo-
rized by the vehicle. When the
12-volt battery is reconnected, the
system will return to the mode it
was in before the 12-volt battery
was discharged. Before discon-
necting the 12-volt battery, turn
the power switch off.
